Question

The transfer of energy in a material medium due to the periodic motion of its particles is called

• A. Stream
• B. wave motion
• C. pulse
• D. none of the above

Answer 1

The correct option is B wave motion

Mechanical wave motion can be defined as the propagation of a disturbance through a material medium due to the repeated periodic motion of the particles of the medium about their mean positions, the disturbance being handed over from one particle to the next.
In this type of wave motion, the particles of the medium vibrate at right angles to the direction of propagation of the wave.
Wave motion is the propagation of a disturbance produced in a medium by the repeated periodic motion of the particles of the medium. In all progressive waves, energy travels through the medium in the direction in which the wave travels. Each particle of the medium has energy of vibration and passes energy on to succeeding particles
